The Integrated Services Routers Generation 2 (ISR G2) provide superior services integration and agility. Designed for scalability, the modular architecture of these platforms enables you to grow and adapt with your business needs.

Table: lists the business benefits of the Cisco 1900. 

Architecture & Modularity
The Cisco 1941 Series is architected to meet the application demands of today’s branch offices with design flexibility for future applications. The modular architecture is designed to support expanding customer requirements, increased bandwidth, and fully integrated power distribution to modules supporting 802.3af Power over Ethernet (PoE) and Cisco Enhanced PoE (ePoE). Table 2 lists the architectural features and benefits of the Cisco 1941 Series

Table 2: Architectural Features and Benefits

Modularity Features and Benefits
The Cisco 1941 provides significantly enhanced modular capabilities (refer to Table 2) offering investment protection for customers. Most of the modules available on previous generations of Cisco routers, such as the Cisco 1841 ISR, are supported on the Cisco 1941. Additionally, modules used on the Cisco 1941 can easily be interchanged with other Cisco routers to provide maximum investment protection. Taking advantage of common interface cards across a network greatly reduces the complexity of managing inventory requirements, implementing large network rollouts, and maintaining configurations across a variety of branch-office sizes. 

A complete list of supported modules is available at http://www.cisco.com/go/1941.

Table 3: Modularity—Features and Benefits

Wireless LAN
The new Cisco 1941W with IEEE 802.11n integrated access point support both unified and autonomous deployments. This integrated Wi-Fi access point offers IEEE 802.11n draft 2.0 standard support for mobile access to high-bandwidth data, voice, and video applications through the use of multiple-input, multiple-output (MIMO) technology that provides increased throughput, reliability, and predictability. IEEE 802.11n wireless networks create a cohesive working environment by combining the mobility of wireless with the performance of wired networks. Cisco has innovative, next-generation wireless solutions that offer greater performance and extended reach for pervasive wireless connectivity. IEEE 802.11n technology delivers outstanding reliability and up to nine times the throughput of current IEEE 802.11 a/b/g networks.

It makes wireless networks an integral part of every type of organization by offering the following benefits:
a. Data rates of up to 600 Mbps support more users, devices, and mission-critical, bandwidth-intensive applications.
b. New MIMO technology provides predictable WLAN coverage and reliable connectivity.
c. Next-generation wireless technology provides superior investment protection to support emerging mobile applications.

These routers help extend corporate networks to secure remote sites while giving users access to the same applications found in corporate offices for both data and voice applications. When users require WLAN access, visibility and control of network security are even more critical at the remote site. The new fixed Cisco Integrated Services Routers meet this need with a single device that combines integrated IEEE 802.11a/b/g/n capabilities with security features such as Wi-Fi Protected Access (WPA), including authentication with IEEE 802.1X with the Cisco Light Extensible Authentication Protocol (LEAP) and Protected EAP (PEAP) and encryption with the WPA Temporal Key Integrity Protocol (TKIP).

Wireless WAN
Cisco third-generation (3G) wireless WAN (WWAN) modules combine traditional enterprise router functions, such as remote management, advanced IP services such as voice over IP (VoIP), and security, with mobility capabilities of 3G WAN access. Using high-speed 3G wireless networks, routers can replace or complement existing landline infrastructure, such as dialup, Frame Relay, and ISDN. Cisco 3G solutions support 3G standards High-Speed Packet Access (HSPA) and Evolution Data Only/Evolution Data Optimized (EVDO) providing you with a true multipath WAN backup and the ability to rapidly deploy primary WAN connectivity. For more information about 3G solutions on Cisco Integrated Services Routers, please refer to http://www.cisco.com/go/3g. 

Integrated LAN Switching
The Cisco 1941 Integrated Services Router Series will support the EHWIC LAN modules when they become available in future. The Cisco 1941 Series support the existing single wide EtherSwitch HWIC and the double wide HWIC-D modules, which greatly expand the router’s capabilities by integrating industry leading Layer 2 or Layer 3 switching. 

Application Services
As organizations continue to centralize and consolidate their branch IT infrastructure in an effort to reduce cost and complexity in the branch office, they are challenged to provide adequate user experience, ensure continuous service availability, and deliver business-relevant applications when and where they are needed. To address these challenges, the Cisco 1941 Series provides the ability to host Cisco, 3rd party, and custom applications on Cisco Services Ready Engine (SRE) module that seamlessly integrate into the router. The module has its own processor, network interface, and memory that operate independently of the host router resources, helping to ensure maximum concurrent routing and application performance while reducing physical space requirements, lowering power consumption, and consolidating management.

Summary and Conclusion
As businesses strive to lower the total cost of ownership in running their network and increase their overall employee productivity with more centralize and collaborative network applications, more intelligent branch office solutions are required. The Cisco 1941 Series offers these solutions by providing enhanced performance and increased modular density to support multiple services. The Cisco 1941 Series is designed to consolidate the functions of separate devices into a single, compact system that can be remotely managed.

A Social Networking Era Ends With MySpace Changes

The legendary New York Yankees catcher Yogi Berra is rumored to have said about a restaurant: “Nobody goes there anymore because it’s too crowded.” That is precisely how I feel about MySpace, cisco product which apparently has a lot of visitors, especially in the U.S., where it is marginally ahead of Facebook, but no one I know actually uses it.

Things are only going to get tougher — Google’s deal with News Corp is going to end soon, and with it a steady spigot of cash will be turned off for a service that is struggling to grow revenues. Like an ’80s rock band, MySpace’s time has come and gone. And nothing reflects that more than the exits of MySpace CEO Chris DeWolfe and his long-time cohort, President Tom Anderson. DeWolfe ran the company from 2003, helped sell it to News Corp for $580 million in 2005 and later helped negotiate a $900 million advertising deal with Google. Since then, MySpace has lost its buzz to Facebook (which is in turn losing that buzz to Twitter). It attempted to become an app platform, but that hasn’t worked out as well. Being a media entrepreneur, I have religiously studied Rupert Murdoch’s career. At the first sign of diminishing returns, Murdoch puts a media entity up for sale, and tries to swap his tin mine for one producing gold. He tried to do that when he attempted to pawn off MySpace to Yahoo.

The clock has been ticking on MySpace and its executives. Earlier this year, COO Amit Kapur and two other long-time MySpace employees left the company because they couldn’t get cisco products the contracts they wanted. Their exit was spun by News Corp. After reading various accounts of DeWolfe’s exit, you can see they left Chris out to dry — something I find particularly distasteful.

Regardless of his exit, there is a strategy in place that could turn MySpace into a decent enough money maker: MySpace Music. By looking to social network’s musical roots, MySpace executives realized that they could build the MTV of the broadband generation. Combining text, audio, video, and social abilities with its audience, MySpace can thrive as a niche yet lucrative musical destination. A lot has to go right for that to happen, though. I have outlined a long list of reservations about MySpace Music.

Back in November 2008, Kevin Kelleher noted, “Social networks spent too much time trying to build audiences without building a solid business model.” With a recession raging and the advertising market in a slump, the social networks have to figure out business models — fast. For MySpace it could mean capturing music industry dollars. MySpace wouldn’t be the first social network looking for niche riches. Hi5, a San Francisco-based social network that’s popular outside of the U.S., recently cut half of its workforce and is said to be pivoting into becoming a social gaming destination. Others are going to soon follow. Folks, what we are seeing is an end of general purpose, broad social networking.

Finally, after nearly two years of us saying so, social is now simply part of the web fabric. Facebook founder Mark Zuckerberg recognized that and since then has been pushing hard on Facebook Connect, which is a simple authentication method that also allows granular social interactions to be embedded in non-Facebook services. With over 200 million Facebookers, Mark has somewhat of a future.

DeWolfe should take this unceremonious exit as a blessing in disguise. Or as Yogi would say, “It gets late early around here…”


Comments
Wonder if Paris Hilton will continue to date Chris after this.

Twitter will take an effect on many of the social networks. Many still don’t understand it, they will soon.

Simon how do you suppose that is going to happen?

Count me as one of those who doesn’t understand.cisco network products How can Twitter supplant the social identity replication serviced by a social network?

Twitter is a content publishing service that, due to the liberty of its usage, has been applied by early adopters as a method of communication, like e-mail. A social identity is much more encompassing than that.

As a musician with 2,500+ Friends on MySpace, I’m happy that Facebook and Twitter are taking so much of the mundane stuff off of MySpace. Personally, I have no interest in Facebook or Twitter because they don’t have musician pages, so if all the non-music fans go there, fine by me. Making MySpace even more music/media oriented sounds great.

“Nobody goes there anymore because it’s too crowded”

Will happen to Facebook too. And I refuse to use any of these lame Social-Networks.
Facebook will be dead in 5 years, less if we are lucky.

In media time and again the “specific always drive out the general.” Here we see it in social networking. cisco reseller I have contended that there are truly riches in niches. I am a fan of social media and I am pulling for MySpace to make this happen. This won’t be the easiest path as they have lived off the fat of the Google deal for some time. They need to move quickly…while not turning away their base. Not easy to do. I am hoping MySpace can pull it off.

Cisco Catalyst 3750 Series Switches, More Popular, Key Features

The Cisco 3750 Switches are innovative switches that improve LAN operating efficiency by combining industry-leading ease of use and high resiliency for stackable switches. And Cisco 3750 series features Cisco Stack Wisetechnology, a 32-Gbps stack interconnect that allows customers to build a unified, highly resilient switching system, one switch at a time.

For mid-sized organizations and enterprise branch offices, the Cisco Catalyst 3750 Series eases deployment of converged applications and adapts to changing business needs by providing configuration flexibility, support for converged network patterns, and automation of intelligent network-services configurations. What’s more, Catalyst 3750 Series WS-C3750G-48PS-S Switch is optimized for high-density Gigabit Ethernet deployments and includes a diverse range of switches that meet access, aggregation, or small-network backbone-connectivity requirements.

So if you are an enterprise branch office, requiring higher quality network services, Cisco 3750 will be a good choice. Need or not? Please check the following feature details:

Key Features & Benefits of Cisco 3750 Switches

Ease of Use: "Plug-and-Play" Configuration
A working stack is self-managing and self-configuring. When switches are added or removed, the master switch automatically loads the Cisco IOS Software revision running on the stack to the new switch, loads the global configuration parameters, and updates all the routing tables to reflect changes. Upgrades are applied universally and simultaneously to all members of the stack.
The Cisco 3750 Series WS-C3750G-48TS-E stacks up to nine switches as a single logical unit for a total of 468 Ethernet or PoE 10/100 ports, or 468 Ethernet 10/100/1000 ports or PoE 10/100/1000 ports, or nine 10 Gigabit Ethernet ports.

Return on Investment through Lower Operations Costs
The automatic Cisco IOS Software version checking and loading of the global configuration parameters provide the first level of operational time saving. The second level is added during the event of an outage. When you remove a troubled switch from an existing stack of switches and replace it with another switch, the master switch will recognize this as a maintenance outage and automatically reload the port-level configuration that was on the previous switch without user intervention. This allows IT managers to have local personnel in remote locations perform maintenance tasks instead of sending costly technicians out for a few minutes of work, thus saving thousands of dollars in operational costs.

Mix-and-Match Switch Types: Pay as You Expand Your Network
Stacks can be created with any combination of Cisco Catalyst 3750 and Cisco Catalyst 3750-E series WS-C3750G-48TS-S. Customers who need a mixture of 10/100 and 10/100/1000 ports, PoE, and wiring-closet aggregation capability can incrementally develop the access environment, paying only for what they need. When uplink capacity needs to be increased, you can easily upgrade your bandwidth by adding a 10 Gigabit Ethernet version to the stack and upgrade your Gigabit Ethernet links with 10 Gigabit Ethernet on the existing fiber.

Availability: Uninterrupted Performance at Layer 2 and Layer 3
The Cisco Catalyst 3750 switch increases availability for stackable switches. Each switch can operate as both a master controller and a forwarding processor. Each switch in the stack can serve as a master, creating a 1:N availability scheme for network control. In the unlikely event of a single unit failure, all other units continue to forward traffic and maintain operation.

Smart Multicast: A New Level of Efficiency for Converged Networks
With Cisco StackWise technology, the Cisco Catalyst 3750 Series offers greater efficiency for multicast applications such as video. Each data packet is put onto the backplane only once, which provides more effective support for more data streams.

Superior Quality of Service Across the Stack and at Wire Speed
The Cisco3750 Series offers Gigabit and 10 Gigabit Ethernet speed with intelligent services that keep everything flowing smoothly, even at 10 times the normal network speed. Mechanisms for marking, classification, and scheduling deliver best-in-class performance for data, voice, and video traffic, all at wire speed.

Network Security: Granular Control for the Access Environment
The Cisco 3750 supports a comprehensive set of security features for connectivity and access control, including ACLs, authentication, port-level security, and identity-based network services with 802.1x and extensions. This set of comprehensive features not only helps prevent external attacks, but also defends the network against "man-in-the-middle" attacks, a primary concern in today's business environment.

Single IP Management: Many Switches, One Address
Each Cisco Catalyst 3750 Series stack is managed as a single object and has a single IP address. Single IP management is supported for activities such as fault detection, VLAN creation and modification, network security, and QoS controls.
cisco 3750 switch


Jumbo Frames: Support for High-Demand Applications
The Cisco3750 Series Switch supports jumbo frames on the 10/100/1000 configurations for advanced data and video applications requiring very large frames.

IPv6 Support
TheCatalyst 3750 Series supports IPv6 routing in hardware for maximum performance. As network devices grow and the need for larger addressing and higher security becomes critical, the Cisco 3750 switch will be ready to meet the requirement.

Standard PoE Support: Graceful Addition of IP Communications
The Cisco Catalyst 3750 and 3750G PoE models support Cisco IP phones and Cisco Aironet wireless LAN (WLAN) access points, as well as any IEEE 802.3af-compliant end device. The Cisco Catalyst 3750 and 3750G 24-port versions can support 24 simultaneous full-powered PoE ports at 15.4W for maximum powered device support. The 48-port versions can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between.

10 Gigabit Ethernet Support: Increased Uplink Bandwidth for Gigabit Ethernet Deployments
The Cisco Catalyst 3750allows network managers to incrementally add IEEE 802.3ae-compliant 10 Gigabit Ethernet connectivity in their wiring closets or grid clusters, further facilitating and enhancing Gigabit Ethernet networks. This provides investment protection to customers who want to use their existing fiber plant, add uplink bandwidth capacity to their switching stacks, and provide higher performance to applications and users.

Management Options
The Cisco 3750 Series switch offers both a superior command-line interface (CLI) for detailed configuration and Cisco Network Assistant Software, a Web-based tool for quick configuration based on preset templates. In addition, CiscoWorks supports the Cisco Catalyst 3750 Series for network wide management.
